摘要

PROBLEM TO BE SOLVED: To provide a lightweight compact inexpensive film-type actuator capable of remarkably expanding a range of application by enlarging the displacement and a working range while keeping the characteristics such as responsiveness and environmental resistance.;SOLUTION: This film-type actuator A is formed by using a high molecular actuator element 1 having an ion exchange resin molded plate 1A capable of being curved and deformed by applying the electric potential difference, and placing an elastic film 3 having an area larger than the high molecular actuator element 1, and displaceable in the same direction in accompany with curving and deforming motion of a free end part 1a of the ion exchange resin molded plate 1A, in a state of covering the high molecular actuator element 1.;COPYRIGHT: (C)2003,JPO
